When you make your report, be sure to note what kind of pipes are used in the attic. Keep in mind that the water could be coming from a vent pipe and water will follow a rafter for a considerable distance before dripping off so look for stains on them.

The attic may be immaterial because they stated that it was the ceiling beneath the second floor bathroom. The only advice we can give you, based on the information you submitted, is to open the ceiling at the leak point and then search for the source of the water. Where it is leaking, however, may not be right below where the leak is.

For the drywall repair, cut the patch a little oversize, trace outline on ceiling, and cut ceiling opening to match patch. Use strips of 3/4 plywood parallel to joists, drywall screwed to the ceiling and then to patch, if the ends are not landing on joists.
